introduction：In practical application，Ac motors are always associated with production machinery，Forming an electric drive system。Different production machines require different speeds，Even the same production machinery in different operating conditions，You need different speeds，Therefore, it is necessary to adjust the speed of the drag system，That is, AC motor speed regulation is generated.Ac motor，Especially the cage induction motor，Because there is no mechanical reversing device，Simple structure、Reliable operation、Easy maintenance、Low cost，And has a good energy saving effect，The single-machine capacity and speed limit are higher than the DC motor;Especially in the dust、In a hostile environment with a risk of explosion，Ac motors are more suitable。But AC motor speed performance is not as good as DC motor，In a long time，Ac motor can only run at constant speed。Solve the problem of AC motor speed regulation，It has always been the topic that electric drive workers pay attention to and study。A brief history of development goes

introduction：The motor made of permanent magnet is called permanent magnet motor，No permanent magnet（electromagnet）Called non-permanent magnet motor；A direct current motor is called a DC motor，No direct current（Alternating current）Its an AC motor。A permanent magnet motor can be a DC motor，It can also be an AC motor（For example, a household breeze ceiling fan）；same，It can be a DC motor without permanent magnets，It can also be an AC motor，Even AC/DC。

introduction： There are two main control methods of DC motor：One is armature voltage control，That is, when the stator magnetic field is unchanged，The speed and output torque of the motor are controlled by controlling the voltage signal applied at both ends of the armature winding；The other is excitation field control，That is, the stator magnetic field strength can be changed by changing the excitation current，Thus control the motor speed and output torque。 When using armature voltage control mode，Because the stator magnetic field remains unchanged，Its armature current can reach the rated value，The corresponding output torque can also reach the rated value，Therefore, this method is also called constant torque speed regulation mode。

introduction：Static index terms： 1、Phase number：Produce different oppositesN、SThe number of excitation coils of a magnetic field。In common usemexpression。 2、beat：The number of pulses or conductive states required to complete a periodic change in the magnetic fieldnexpression，Or refers to the number of pulses required by the motor to rotate a pitch Angle，Take the four-phase motor as an example，There are four phases and four beats in operationAB-BC-CD-DA-AB，The four-phase eight-beat operation mode is A-AB-B-BC-C-CD-D-DA-A。 3、Step Angle：Corresponds to a pulse signal，The angular displacement of the rotor of the motorθexpression。θ=360The degree of/（Number of rotor teeth*Running beat），Conventionally two、four-phase，Rotor teeth are50Tooth motor for example。The step Angle of the four-beat running time isθ=360The degree of/（50*4）=1.8The degree of（pacing），The step Angle of eight-beat running time isθ=360The degree of/（50*8）=0.9The degree of（half-step）。
